    Abaco, an ultra fast number parser for Buffers. It parses a Buffer, or a portion of it, to get the Number value stored as (ASCII) String.

    It is faster than parseInt(), parseFloat() and Number() constructor to convert a String or a Buffer to a usable Number.

    NOTE: It adds the ability to parse a float with a radix argument, as for #parseInt.

    Install

    $ npm install abaco [-g]
    // clone repo
    $ git clone git@github.com:rootslab/abaco.git

    require returns an helper hash/obj.

    var Abaco  = require( 'abaco' );

    Run Tests

    cd abaco/
    $ npm test

    Run Benchmarks

    cd abaco/
    $ npm run-script bench

    Sample Usage

    See examples.

    Methods

    Arguments within [ ] are optional.

    /*
     * Parse a Buffer that contains string representation of an integer Number.
     * If radix is not specified, it defaults to 10; possible radix value range
     * is between 2 and 16.
     * If begin or end are not specified, it parses the entire Buffer.
     *
     * NOTE: js number precision is limited to ~ 2^53 or 10^16, it means, for example,
     * that the limit for decimal numbers is 16 bytes/chars; so it returns NaN for
     * values out of this range. NaN also signals that is better to use raw String,
     * because number representation is not accurate. See 'bl' table in the code to
     * check bytes limit for every radix.
     *
     * NOTE: Only '-' prefix is supported, no 0x' or '0' prefix, for hex or octal
     * digits; just use the begin offset for skipping some bytes.
